Abstract

Récupération de l'uranium contenu dans une solution brute d'acide phosphorique. On met en contact la solution brute, avec un agent d'extraction organique formé d'acide octyl-phénylphosphorique d'acide bis-(2-éthylhexyl)-phosphorique et oxyde de trioctylphosphine dans un diluant organique puis on réextrait l'uranium sous forme de fluorure. On évite l'emploi de fer comme réducteur et l'on réduit les risques de corrosion de l'appareillage.Recovery of the uranium contained in a crude solution of phosphoric acid. The crude solution is brought into contact with an organic extractant formed from octyl-phenylphosphoric acid, bis- (2-ethylhexyl) -phosphoric acid and trioctylphosphine oxide in an organic diluent and then the uranium is reextracted in the form fluoride. The use of iron as a reducing agent is avoided and the risks of corrosion of the equipment are reduced.
